Cannot decide which track to take in LCS

I’m starting LCS next month. This is such a big deal for me because it’s a second career, I’m 52, in a lot of debt and scared shitless:)
I am not sure if I should work for the LCS so that I can acquire a lot of experience and not have to worry about marketing or walk through my fears of going out on my own.
I’m completely emotionally exhausted from my current career. I don’t believe that’s a thought. I work in an emotional trauma center and the stories we hear which are horrific, along with treating clients who are non functional is very draining. I want to leave and be a life coach ASAP but also want to be smart about it.
Any suggestions?
Thank you
